2. entreat, pray, beseech, petition. Beg and request are used in certain conventional formulas, in the sense of ask.Beg, once a part of many formal expressions used in letter writing, debate, etc., is now used chiefly in such courteous formulas as I beg your pardon; The Committee begs to report, etc. Request, more impersonal and now more formal, is used in giving courteous orders (You are requested to report ) and in commercial formulas like to request payment.

beg

v.

c.1200, perhaps from Old English bedecian "to beg," from Proto-Germanic *beth-; or possibly from Anglo-French begger, from Old French begart (see beggar). The Old English word for "beg" was wædlian, from wædl "poverty." Of trained dogs, 1816.

As a courteous mode of asking (beg pardon, etc.), first attested c.1600. To beg the question translates Latin petitio principii, and means "to assume something that hasn't been proven as a basis of one's argument," thus "asking" one's opponent to give something unearned, though more of the nature of taking it for granted without warrant.

That the poor existed among the Hebrews we have abundant evidence (Ex. 23:11; Deut. 15:11), but there is no mention of beggars properly so called in the Old Testament. The poor were provided for by the law of Moses (Lev. 19:10; Deut. 12:12; 14:29). It is predicted of the seed of the wicked that they shall be beggars (Ps. 37:25; 109:10). In the New Testament we find not seldom mention made of beggars (Mark 10:46; Luke 16:20, 21; Acts 3:2), yet there is no mention of such a class as vagrant beggars, so numerous in the East. "Beggarly," in Gal. 4:9, means worthless.

beg the question

Take for granted or assume the truth of the very thing being questioned. For example, Shopping now for a dress to wear to the ceremony is really begging the question—she hasn't been invited yet. This phrase, whose roots are in Aristotle's writings on logic, came into English in the late 1500s. In the 1990s, however, people sometimes used the phrase as a synonym of “ask the question” (as in The article begs the question: “What are we afraid of?”).
